Description

Technical Field

[0001] The present invention relates to the technical field of container anti-theft doors, and in particular to an image recognition-based container anti-theft door and a method of using the same. Background Art

[0002] Recently, security doors with the ability to receive goods or couriers have become increasingly popular. For example, Chinese patent CN215369515U discloses a security door with a function for receiving and placing couriers. This door features a box or cabinet mounted on the security door for receiving goods, with the door of the box or cabinet nested within the security door itself. This security door is equipped with both a security door lock and a container door lock to lock the security door and the cabinet door above it, respectively. The container door lock can be controlled by the homeowner's mobile phone, enabling efficient receipt of goods or couriers. This ensures safety and security while also enabling convenient and quick delivery of couriers when no one is home.

[0003] With the advancement of technology, security door locks are becoming increasingly intelligent and user-friendly. Currently, new technologies such as fingerprint recognition and facial recognition are gradually being applied to the security door industry. With these technologies, homeowners no longer need to enter cumbersome passwords to unlock their security doors, significantly improving the user experience of smart security doors.

[0004] However, the introduction of new technologies also brought new problems: the two sets of door locks on the container security door required different unlocking settings to control the locking of the security door body and the container door respectively. For example, the two sets of door locks required different keys or passwords for opening and closing; the two sets of door locks could also register different fingerprints for opening and closing. However, when using facial recognition to lock both sets of door locks, since people only have one face, if it is applied to both sets of door locks simultaneously, it would be difficult for the security door lock's master control program to determine whether the owner intended to open the security door or the container door, resulting in mislocking and severely reducing the user experience.

[0005] Chinese patent CN119251935A discloses a facial recognition-based container security door and its use method. The design reserves a period of time after facial recognition is completed. If a person enters an operating instruction on the keyboard of the security door during this reserved time, the container door will open. If no operating instruction is entered during the reserved time, the security door will open. This approach solves the problem of one face not being able to open two doors. However, the above solution still has a problem: in the actual production of container security doors, facial recognition is based on an image recognition chip and system, while keyboard operation is based on a digital password chip and system. These two components are typically supplied by two different manufacturers. Once these two components are integrated into the container security door, and the system integration of different components from different manufacturers is not considered, if one of the components fails, the container door will be difficult to open normally. Summary of the Invention

[0006] In view of this, the present invention proposes a container anti-theft door based on image recognition and a method of using the same, which is used to solve the problem that after different components from different manufacturers are integrated into the container anti-theft door, problems with any component will cause the container door to be unable to open normally.

[0007] The technical solution of the present invention is implemented as follows: the present invention provides a container anti-theft door based on image recognition, including an anti-theft door; a container door, which is arranged on the side of the anti-theft door facing the outside; a camera, which is arranged on the anti-theft door and is used to capture facial images and palm print images; a first control system, which is arranged in the anti-theft door and electrically connected to the camera, and the first control system recognizes image information and controls the opening and closing of the anti-theft door and the container door; a database, which is arranged in the anti-theft door and electrically connected to the first control system, and the database stores image information pre-registered by the householder, and the first control system matches the facial image or palm print image captured by the camera with the image information in the database; a power supply, which is arranged in the anti-theft door and electrically connected to the first control system, and the power supply is used for power supply.

[0008] On the basis of the above technical solution, preferably, it also includes a second control system, which is arranged in the anti-theft door and electrically connected to the database and the power supply. The second control system receives and processes the password data and operation instructions input by the keyboard, and controls the opening and closing of the anti-theft door and the container door; an operation screen is arranged on the anti-theft door and electrically connected to the first control system and the second control system. The operation screen displays the image information captured by the camera or displays the keyboard; wherein the database also stores the password information pre-registered by the householder, the second control system matches the password data input by the keyboard with the password information in the database, and the first control system also receives and processes the operation instructions input by the keyboard.

[0009] On the other hand, the present invention also provides a method for using a container security door based on image recognition, which uses the above-mentioned container security door based on image recognition, including the following steps: S1, when a person stands in front of the security door, the camera captures facial image information and transmits it to the first control system, the operating screen displays the captured image, and the first control system matches the facial image with the image information pre-registered by the householder in the database; S2, if the match is successful, the camera captures the image again, and the operating screen displays the captured image at the same time. The first control system is set with a preset time and starts timing from when the camera captures the image again; S3, within the preset time, the first control system repeatedly captures the image and matches the captured image with the palm print image information pre-registered by the householder in the database. The first control system determines whether to unlock the security door or container door based on whether the captured image is a palm print image and whether the palm print images match.

[0010] On the basis of the above technical solution, preferably, in step S2, when the facial image is matched successfully, the operation screen automatically wakes up and displays the keyboard, and the second control system is set with a preset time and starts timing from the time the operation screen wakes up; in step S3, before the palm print image matching is completed, within the preset time, the second control system determines whether the registrant enters an operation instruction on the keyboard to unlock the anti-theft door or container door.

[0011] More preferably, in step S1, before the facial image matching is completed or after failure, click to wake up the operation screen and display the keyboard, enter the password through the keyboard, and the second control system matches the password data with the password information pre-registered by the householder in the database.

[0012] More preferably, in step S2, when the first control system determines that the facial image information matching fails, or when the second control system determines that the password information matching fails, the operation screen is always dark or has no response to touch.

[0013] More preferably, in step S2, the preset time of the first control system or the second control system is 1s to 2s.

[0014] Further preferably, in step S3, when the facial image is matched successfully, the palm print image is matched successfully within a preset time, or an operation instruction is input on the keyboard of the operation screen within the preset time, the container door is unlocked; if the palm print image fails to match within the preset time, or there is no operation within the preset time, the anti-theft door is unlocked.

[0015] More preferably, the keyboard displayed on the operation screen is provided with preset buttons, and operation instructions are input by clicking the preset buttons on the keyboard of the operation screen.

[0016] More preferably, the keyboard for operating the screen is a twelve-key numeric keyboard, and the preset key is the asterisk key.

[0017] The image recognition-based container anti-theft door and its use method of the present invention have the following beneficial effects compared with the prior art: (1) The present invention uses facial recognition combined with palm print recognition to respectively associate and unlock the security door and the container door, and sets the response time of palm print recognition. If the palm print image is successfully matched within the preset time, the control system can judge that the container door is open based on this. If the palm print image fails to match within the preset time, the security door is opened. Since the facial recognition machine and palm print recognition are based on the same image recognition system, the opening and closing of the security door and the container door are avoided by being controlled by two control systems, which would cause the container door to be unable to open due to failure of either system.

[0018] (2) In addition to the image recognition system, the present invention also has a control system that uses digital passwords and operating instructions to respectively unlock the anti-theft door and the container door. There is also an interactive design between the two systems, which greatly expands the control method for selecting to open the container door. At the same time, it ensures that if any system has a problem, the other system as a backup can still effectively select the normal opening and closing of the anti-theft door and the container door.

[0019] (3) The present invention sets the preset time to 1s to 2s based on the user's reaction time. The time will not be too short to cause the operator to react in time, nor will it be too long to increase the probability of misoperation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, combined Figure 2 The present invention provides a container anti-theft door based on image recognition, including an anti-theft door 1, a container door 2, a camera 3, a first control system 4, a database 5 and a power supply 6.

[0025] The security door 1 is the main body of the container security door, mounted on the main door frame. Because it includes storage space, it is slightly thicker than conventional security doors, but this should not hinder the normal opening and closing of the container security door. A lock is installed on the security door 1 to lock it. The security door 1 typically has a handle, which can be equipped with a fingerprint unlocking function.

[0026] Container door 2 is located on the side of security door 1 facing outdoors. It serves to enclose the storage space. To reduce the overall weight of the container security door, container door 2 is typically thin. A lock is installed on container door 2 to secure it. A concealed handle is typically provided on container door 2 to enhance the overall aesthetics of the container security door.

[0027] The camera 3 is mounted on the security door 1 and is used to capture facial images and palm print images. The camera 3 is generally positioned at an adult height above the ground. The camera 3 may be an infrared camera to facilitate image recognition and capture in dark or low-light environments such as at night.

[0028] The first control system 4 is arranged in the anti-theft door 1 and is electrically connected or communicatively connected to the camera 3; the first control system 4 is a chip, algorithm and system based on image recognition, so the function of the first control system 4 is to recognize image information and control the opening and closing of the anti-theft door 1 and the container door 2.

[0029] The database 5 is provided inside the security door 1 and is electrically connected to the first control system 4. The database 5 stores the image information pre-registered by the householder. The first control system 4 matches the facial image or palm print image captured by the camera 3 with the image information in the database 5. The database 5 can be a data hard disk.

[0030] The power supply 6 is provided in the anti-theft door 1 and is electrically connected to the first control system 4. The power supply 6 supplies power to each power-requiring component. The power supply 6 can be a battery pack installed at the bottom of the anti-theft door 1.

[0031] In actual production, products from different suppliers are designed and maintained by different technical teams. Therefore, integrating products from different suppliers into a system can be difficult to ensure that operational errors will not occur when the two systems are connected. Furthermore, when an operational error occurs in the integrated product, it is difficult to determine which system is responsible, further increasing maintenance costs and difficulty. In this embodiment, facial recognition and palmprint recognition are both based on image recognition technology. Therefore, image recognition components from a single supplier can be used to perform both facial and palmprint recognition functions within the same first control system 4. Even if an operational error occurs within the first control system 4, the root cause can be quickly identified because the system was designed and developed by a single supplier, reducing maintenance costs and difficulty. Therefore, this design not only eliminates the difficulty of integrating multiple systems, but also eliminates the problem of the container door 2 being unable to open due to a failure in either system, as the security door 1 and container door 2 are each associated with different algorithms and logic.

[0032] exist Figure 2 In the preferred embodiment shown, a second control system 7 and an operation screen 8 are also included.

[0033] The database 5 also stores password information pre-registered by the householder.

[0034] Second control system 7 is located within security door 1 and is electrically connected to database 5 and power supply 6. Second control system 7 is based on digital password-related chips, algorithms, and systems. Its functions include receiving and processing password data and operating instructions input via the keyboard, while also controlling the opening and closing of security door 1 and container door 2. Generally speaking, first control system 4, database 5, and second control system 7 can be housed within the same internal housing of security door 1.

[0035] An operation screen 8 is provided on the security door 1 and is electrically connected to both the first control system 4 and the second control system 7. The operation screen 8 may be a touch screen. The operation screen 8 displays image information captured by the camera 3 or displays a keyboard with virtual keys. The camera 3 and the operation screen 8 may be provided on the same operation panel.

[0036] The first control system 4 also receives and processes the operation instructions input by the keyboard; the second control system 7 matches the password data input by the keyboard with the password information in the database 5.

[0037] In addition to the first control system 4, this embodiment also includes another digital password-based control system, namely, the second control system 7. These two systems can operate independently or interact with each other. A problem in either system will not affect the other system's control over the opening and closing of the security door 1 and the container door 2. Therefore, the two systems serve as backups for each other. Furthermore, each system can be maintained by its own supply team, significantly reducing maintenance difficulty and costs.

[0038] like Figure 4 As shown, combined Figure 1 and 2 The present invention further provides a method for using a container security door based on image recognition, which uses any of the above-mentioned embodiments of a container security door based on image recognition. This embodiment uses a single first control system 4 to control the opening and closing of the security door 1 and the container door 2, and includes the following steps: S1: When a person stands in front of security door 1, camera 3 captures a facial image of the person and transmits it to first control system 4. Operation screen 8 displays the captured image, and first control system 4 matches the facial image with the householder's pre-registered image information in database 5. The householder's pre-registered image information includes facial images and palm print images of the householder and his / her relatives.

[0039] S2, if the match is successful, the anti-theft door 1 enters the pre-unlock state, and the camera 3 starts to capture images again. This time, the camera 3 captures the palm print image. Specifically, the user needs to raise one of the palms to show the palm print, and then make the palm face towards the camera 3 and slowly make a fist. The operation screen 8 displays the captured image at the same time. The first control system 4 is set with a preset time and starts timing from when the camera 3 starts to capture images again.

[0040] S3: Within a preset time, since it takes a certain amount of time for the user to present their palm print to camera 3, camera 3 will continue to capture images within the preset time. First control system 4 repeatedly captures images and continuously matches them with the householder's pre-registered palm print image information in database 5. First control system 4 determines whether to unlock security door 1 or container door 2 based on whether the captured image is a palm print image and whether the palm print images match. Specifically, within the preset time, if the palm print image matches successfully, it indicates that the user has made an action command to open container door 2, so first control system 4 controls container door 2 to open. If the palm print image matches unsuccessfully, it indicates that the user's action command is not standardized, or the user does not intend to open container door 2 and has not presented their palm print, so first control system 4 controls security door 1 to open.

[0041] exist Figure 4In a preferred embodiment shown, in step S2, after a successful facial image match, the user may enter an incorrect action command within a preset time. Therefore, another method is required to ensure that the container door 2 can be opened, and this method is controlled by the second control system 7. In this embodiment, the operating screen 8 automatically wakes up and displays the keyboard. The second control system 7 is set with a preset timer that starts counting from the time the operating screen 8 wakes up. In step S3, before the palm print image match is completed, within the preset time, the second control system 7 determines whether the registered person enters an action command on the keyboard to unlock the security door 1 or the container door 2. Because the second control system 7 is based on a digital password algorithm system, the action command of the second control system 7 is input via keyboard. This method has a low probability of input errors and a clear judgment standard: either the door is opened by key input, or the door will not be opened if the key is not touched. This ensures that the container door 2 can be opened by the second control system 7.

[0042] exist Figure 4 In a preferred embodiment shown, the second control system 7 can also independently open and close the anti-theft door 1. In step S1, before the facial image matching is completed or after failure, click to wake up the operation screen 8 and display the keyboard. Enter the password through the keyboard. The second control system 7 matches the password data with the password information pre-registered by the household owner in the database 5. Therefore, the control method of the second control system 7 to open the anti-theft door 1 is conventional password unlocking, which is more secure and accurate.

[0043] exist Figure 4 In a preferred embodiment shown, in step S2, when the first control system 4 determines that the facial image information match fails, or when the second control system 7 determines that the password information match fails, the operation screen 8 is always dark or unresponsive to touch, thereby avoiding frequent false responses of the operation screen 8 and consuming power.

[0044] exist Figure 4 In a preferred embodiment shown, the preset time should not be too short, as it will not give the user enough time to react; nor should it be too long, as it will greatly increase the probability of misoperation. In step S2, the preset time of the first control system 4 or the second control system 7 is 1s~2s, preferably 1.5s.

[0045] exist Figure 4In a preferred embodiment shown, in step S3, if facial image matching is successful, palm print matching is successful within a preset time, or an operation command is entered on the keyboard of operation screen 8 within a preset time, container door 2 is unlocked. If palm print matching fails within the preset time, or if no operation is performed within the preset time, security door 1 is unlocked. The first control system 4 and the second control system 7 each control the independent unlocking of the two security doors 1 and container door 2 using their own built-in judgment criteria.

[0046] exist Figure 3 In a preferred embodiment shown, preset buttons are provided on the keyboard displayed on the operation screen 8. Operation instructions are input by clicking a preset button on the keyboard of the operation screen 8. The method of inputting operation instructions is extremely convenient and easy to remember.

[0047] exist Figure 3 In a preferred embodiment shown, the keyboard of the operation screen 8 is a twelve-key numeric keyboard, i.e., it includes numbers from 0 to 9 and a pound key and an asterisk key; generally speaking, when entering a password to unlock the door, it ends with the pound key, so in order to distinguish it, the preset key can be set as the asterisk key, which also makes the method of entering operation instructions extremely convenient and easy to remember.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
